deleting current active connections on a BigIP

i did delete only the ssh connection with the command:

 

 

b conn client 10.10.4.30 server 10.10.4.31:22 delete

 

 

but one question with the VE 10.1 trial

 

 

i open a conection with the vs 10.10.4.100 port 443 and with source persist

 

 

the persist work 100%, but in the cli with the command b conn client 10.10.4.30 or b conn server 10.10.4.100 some time i see the conenction and sometimes not

 

 

is there one limitation of trial ?

 

 

thanks
